Hello! It is a symptom of grape blight, which mainly damages the cob, stalk and fruit grains, and sometimes also the leaves.
At the beginning of the disease, there are irregular colored lesions at the base of the small fruit peduncle, and there is an inconspicuous dark brown halo on the edge, which gradually expands, and the fruit stem is circumcised, causing the fruit to lose water and wilt. In the later stage, it gradually dries and shrinks, turning into purple-black stiff fruit, and produces sparse small black spots on the surface of the diseased fruit, that is, the spore organ of the pathogen. The stiff fruit hangs on the branch for a long time, which is one of the main differences between the disease and anthracnose and white rot.
When the leaf is susceptible, it produces small round black-brown spots on the leaves, which turn grayish-white in the middle, and dense small black spots on them, which are the conidia and ascomycetes of the pathogen.
Pesticide control: spray 1 time of 5 Baumé stone sulfur mixture before the grape is buried in the soil to prevent cold; If the disease is severe, when the scales of grape buds are enlarged in early spring, spray 2 3 Baumé stone sulfur mixture plus sodium pentachlorophenol for a better effect. or a single spray of 3 5 Baumé stone sulfur mixture, or 200 300 times of sodium pentachlorophenol plus 1 Baumé stone sulfur mixture; or 25% of the rot (biguanide salt) 200 400 times the solution, to eliminate overwintering pathogenic bacteria, and to treat rust ticks, scale insects, etc.

Hello, generally fruit trees have fruit drops, that's normal.
The first fruit drop is caused by poor pollination and fertilization, and the second fruit drop is caused by insufficient nutrition (too many results are not necessarily all good things, Zheng hunger bears too many fruits, and too much nutrient consumption will cause the fruit to be small and the tree to decline too quickly). These are normal physiological phenomena that do not have to be solved by any means.
However, if the fruit is less and the fruit falls or a large number of fruit drops, there are generally the following phenomena called back to cause: the introduction of pests and diseases such as aphids, insects, etc. or downy mildew, powdery mildew, etc., pests can be sprayed with pesticides, the selection of pesticides is: emamectin salt insecticide, imidacloprid to kill aphid insects, Kelu prevention and control of downy mildew, Jiatuo prevention and treatment of powdery, black star and other diseases, the second is the introduction of insufficient fertilizer and water, water-soluble fertilizers can be applied, such as Haihewei water-soluble fertilizer, foliar spray sea meal fertile foliar fertilizer containing amino acids + boron fertilizer + powder potassium dihydrogen phosphate, to promote fruit trees to protect flowers and fruits.

Some people know about grapes, some know about saplings, and many more don't know about the tree grape species. So what is a tree grape? For netizens who don't know, let's follow my footsteps to find out.
1. Tree grapes, also known as Garbo fruit, are native to Brazil, Bolivia, Paraguay and eastern Argentina in South America.
2. Taiwan was the first to introduce planting in the 60s of the 20th century, and then gradually spread in a few decades, and now China's Fujian, Zhejiang, Guangdong, Sichuan, Hubei, Guangxi, Jiangsu and Yunnan and other places have the planting of tree grapes.
3. Grape is an evergreen shrub, the growth is very slow, if it is a newly planted seedling, it needs to wait until five years later to bear fruit, but the yield at the beginning of the fruit is very unstable, sometimes it will bear a lot, but maybe only one or two, affected by the climate of the year.
After reading this, are you tempted by tree grapes? Except for the growth period is longer, other aspects can be said to be widely used. If you are patient, you can buy a sapling and plant it yourself.

Summary. The case was implemented on a platform called the Hehui Ecological Vineyard app. The platform claims that as long as you can earn commissions by buying and selling virtual vines, the operation is simple and easy to understand, you can use your mobile phone to make a lot of money at home, if the user develops downline, the superior can also extract a certain percentage of the marketing profit from the lower, the more the downline profits, the more profit they make.
Many victims do profit from it at first, but over time, it is difficult to get rid of this virtual "vine". Zhou Senlei, a police officer at the Lushan Police Station, told reporters: "In order to obtain more profits, many people will participate in their own participation, and will mobilize relatives and friends to participate together, the platform was launched around March last year, when many citizens were 'staying' at home, coupled with the sense of trust brought by relatives and friends, there are not a few people who have been deceived."
Behind the online purchase of grapevines, there is a hidden legend of Kai Jian's slip pin**? A few days ago, the Economic Investigation Brigade of the Shengzhou City Public Security Bureau cracked a pyramid scheme case under the guise of buying and selling grapes to change trees, and all six people involved in the case, including Yu, have been transferred to the Municipal People's Procuratorate for prosecution.

MLM ** is full of tricks, and it has been repeatedly banned, and I don't guess that Xianzhou only harms myself, but also affects relatives and friends. Everyone must be cautious and cautious, strengthen screening, and do not be deceived by greedy for small profits.
The root system of the grape is made up of the root trunk, root neck, lateral roots, fine roots and root hairs. The root stem mainly plays the role of fixing the plant, and at the same time has the function of storing nutrients and transporting water and nutrients. Lateral roots and fine roots transport the absorbed minerals to the root stem through water, and convert the inorganic nitrogen, inorganic phosphorus and other substances absorbed in the soil into organic nitrides and organic phosphorus. The absorption of grape roots is mainly carried out by the young roots that have just emerged, which are fleshy, white or yellowish in the early stages of formation. >>>More
Hard disk master and slave jump error is a very likely problem, and COMS can also be set to boot from the main disk or from the disk boot or other boot, you see if your hard disk jumper is not on the CS, this is automatic, the system will automatically recognize, and then change the first boot to HDD-0 in the coms, and then restart, if you have installed the system, it should be able to boot, if not, reinstall it once.
